CTB - A Final Fantasy X-like Battle System, Version 3.2

[skrotkanon]

After trying to get this to work for a few hours I ran into the following message;

Script 'Bar 1.4.1' Line 47: FloatDomainError occured.

NaN

The line is this -
dest = Rect.new(@x+(4*x_ratio).ceil, @y+(4*y_ratio).ceil, ((@width-8*x_ratio)*value/max).ceil, (@height-8*y_ratio))

Otherwise I've been able to poke around a bit to fix minor problems but I have no idea what this evem means. I did look it up and the only thing I was able to find was that NaN stands for "Not A Number" whatever that means. I have no knowledge of Ruby so this is just confusing, especially since I have no idea what the Bar 1.4.1 thing even does.

I'd be really happy if someone could take a look at this. I haven't poked around much in the codes, I just took out Extended Party Support and Support For HP Bars since I couldn't even start the game with those in.

If you want to know I'm using the following addons;
- Advanced Analyze System by Blizzard
- Easy Party Switcher by Blizzard
- Advanced Time and Environment System (ATES) by Blizzard
- UMS by Ccoa
- Random Movement Fix by sandgolem
- Multi-Slot Equipment Script by Guillame777
- Escape Bar Removal Code by DerVVulfman
- Minkoff Animated Battlers by DerVVulfman
- Stormtronics CMS by Blizzard

Thanks in advance!
